Xomnia vs Sigma Software: pros and cons

| + | 2025 Aurai acquisition materially increased delivery capacity and breadth |
| + | EU-hosted cloud solutions directly address data-residency concerns for Dutch and EU clients |

| - | Public information on a dedicated AI/ML practice or named AI case studies is less detailed than several boutique competitors on this list |
